inductar® ONH cube

Simultaneous ONH elemental analysis in metals and ceramics

The inductar ONH cube is an innovative elemental analyzer, which is able to analyze oxygen, nitrogen and hydrogen concentrations in inorganic materials simultaneously. This high-precision ONH analyzer for metallic or ceramic materials uses only state-of-the-art technologies. It is equipped with a long-life solid-state high-frequency induction furnace, which makes it possible to reach sample temperatures of up to 3000 °C. Thanks to an optional camera the gas release can be observed in real-time by the operator. Also for the element detection advanced technologies are used. Oxygen is analyzed by a wide-range IR detector, which is capable to detect the whole concentration range. For the precise hydrogen analysis a unique electrochemical detection technology finds usage for the first time. The nitrogen analysis by a well-known thermal conductivity detector completes the precise and simultaneous 3-element analysis of oxygen, nitrogen and hydrogen in one cycle.

Innovative design and technology solutions for highest precision

The innovative design with its feeding system from top and intelligent gas flow direction reduces dust and debris to a minimum. This ensures high tidiness within the whole device, which makes any tedious cleaning operation unnecessary. Together with tool-free maintenance and intuitive, multi-language software, the inductar ONH cube is really easy to use. Moreover, the optional 50 position autosampler allows a fully automated high-throughput operation. Due to its high precision, maximum user convenience and maximum robustness in 24/7 operation, the inductar ONH cube fulfills all requirements for sophisticated R&D projects and daily routine operation as well. For those who wish to analyze even up to 5 elements with one and the same device, the inductar ONH cube can be upgraded anytime to the inductar EL cube.

The inductar ONH cube is optimized for simultaneous oxygen, nitrogen and hydrogen analysis.

We offer an automated version with 42 sample positions as well as a manual version with 2 sample positions.

Measuring methodFusing under Helium or Argon at up to 3000 °C followed by purification of the analytical gas flow and subsequent gas analysis. ON-analysis is done according to international standards. H-analysis can also be done according to standards.

Easy sample preparation and handlingWithout any special sample preparation, all kinds of solid samples are weighed into graphite sample containers (weight up to 1 g). For some analyses additives need to be added.

Innovative technologyThe inductar ONH cube is the first ONH-analyzer that works with a solid-state inductions furnace and is able to detect all three elements simultaneously. The hydrogen content is quantitatively measured with an electrochemical cell.

Linear single/multipoint-calibrationThe operator is guided through the calibration by an intuitive calibration assistant. The transparently calculated calibration is editable and storable. Furthermore, templates can be stored for future calibrations. Calibration is linear and stable for months.

Few operational requirements1 m laboratory working space, one electrical connection and one operating gas are sufficient for long term operation.

Optical camera:An optical camera is available for observation of the fusion process.

Electronic analytical balance:The balance and elemental analyzer form a system.We offer convenient analytical balances from the leading manufacturers with our instruments.

Nickel capsule press:In order to securely close the nickel capsules with mainly powder sample material inside, we recommend to use Elementar’s nickel capsule press. This press helps to smoothly and easily close the nickel capsules.

Our kits of consumables contain all necessary parts and chemicals for the corresponding mode, such as combustion/reaction tubes, all chemicals and instrument specific wear parts. We do not compromise on quality of the used parts and chemicals – this is the prerequisite of a guaranteed long lifetime of our instruments.

For oxygen, nitrogen and hydrogen analysis the following consumables are needed:
